Abstract
In an automatic fastener assembling machine, an automatic lower-fastener-element supply apparatus includes a guide member horizontally reciprocable in timed relation to vertical movement of a punch, and a die supported by the guide member and movable, in response to reciprocating movement of the guide member, between a fastener transfer position in which the die is contiguous to the lower end of a chute to receive a lower fastener element therefrom, and a fastener joining position in which the die is vertically aligned with the punch.
Claims6
A machine for automatically assembling a pair of upper and lower fastener elements of a garment fastener with a garment fabric sandwiched between the upper and lower fastener elements, comprising:
- (a) a frame;
- (b) a pair of first and second chutes for feeding therealong successive upper fastener elements and successive lower fastener elements, respectively;
- (c) an upper unit supported by said frame for receiving the successive upper fastener elements one at a time from said first chute, said upper unit including a ram reciprocably supported by said frame and a punch mounted on said ram for vertical movement in response to reciprocating movement of said ram;
- (d) a first drive means operatively connected with said ram for reciprocating the latter vertically;
- (e) a fastener holding member disposed contiguous to a lower open end of said second chute for temporarily holding the successive lower fastener elements one at a time from said second chute;
- and
- (f) a lower unit including
- (1) a support block fixed to said frame,
- (2) a horizontal guide member slidably supported on said support block,
- (3) a second drive means operatively connected with said guide member for reciprocating the latter linearly and horizontally in time relation to the vertical movement of said punch,
- (4) a die supported by said guide member and movable, in response to the reciprocating movement of said guide member, between a fastener transfer position in which said die is vertically aligned with said fastener holding member to receive the lower fastener element therefrom, and a fastener joining position in which said die is vertically aligned with said punch and is spaced from said support block, and
- (5) a die holder fixed to one end of said guide member, said die being pivotally mounted on said die holder and movable between an inclined position and a horizontal position.
